1 Well Drilling Questions

How deep should a well be in Southern California?

Well depth in Southern California varies significantly by location:

  • Ramona/Valley Center: 300-500 feet average
  • Julian/Mountain areas: 200-400 feet
  • Anza/Aguanga: 200-600 feet
  • Temecula/Murrieta: 300-600 feet
  • Coastal areas: 100-300 feet

We review well logs from neighboring properties to estimate depth before drilling.

How much does it cost to drill a well?

Well drilling costs in San Diego and Riverside Counties typically range from $15,000 to $50,000+, depending on:

  • Depth required: $25-$50 per foot for drilling
  • Geology: Hard rock costs more than soft formations
  • Equipment: Pump ($1,500-$3,000), pressure tank ($300-$800)
  • Permits: $500-$1,500 depending on county

How long does it take to drill a well?

The drilling process typically takes 1-3 days for the actual drilling, plus additional time for:

  • Permit approval: 2-6 weeks
  • Well development: 1 day
  • Pump installation: 1 day
  • Water testing: 1-2 weeks for results

Total timeline from start to running water: 4-8 weeks

Do I need a permit to drill a well?

Yes. Both San Diego and Riverside Counties require well permits. The process includes:

  • Application with property survey
  • Site plan showing well location
  • Setback requirements (from septic, property lines)
  • County health department approval

We handle all permit paperwork for our customers.

2 Pump & Equipment Questions

How long does a well pump last?

A quality submersible pump typically lasts 8-15 years. Factors affecting lifespan:

  • Water quality: Sand/sediment reduces life
  • Proper sizing: Oversized pumps cycle too often
  • Electrical: Voltage fluctuations cause damage
  • Usage: Heavy use = shorter life
→ Signs your pump is failing
How much does a new well pump cost?

Well pump replacement typically costs $1,500-$4,000 installed, depending on:

  • Pump type: Submersible vs jet pump
  • Well depth: Deeper = more expensive
  • Horsepower: 1/2 HP to 2 HP
  • Brand: Grundfos, Franklin, Goulds

Why is my well pump running constantly?

A pump that won't shut off usually indicates one of these problems:

  • Leak in the system: Check for wet spots
  • Waterlogged pressure tank: Most common cause
  • Bad pressure switch: Not sensing pressure correctly
  • Failing pump: Can't build pressure
  • Low water level: Well may need deepening

⚠️ A constantly running pump will burn out quickly. Call for service promptly.

What size pressure tank do I need?

Pressure tank size depends on your pump's GPM (gallons per minute):

  • 5-10 GPM pump: 20-30 gallon tank
  • 10-15 GPM pump: 30-50 gallon tank
  • 15-25 GPM pump: 50-85 gallon tank

Larger tanks reduce pump cycling and extend pump life.

3 Water Quality Questions

How often should I test my well water?

The EPA recommends this testing schedule:

  • Annually: Bacteria (coliform) and nitrates
  • Every 3-5 years: Full mineral panel, pH, hardness
  • Immediately if: Change in taste, smell, or color
  • After repairs: Always test after pump work
→ Complete water testing guide
Why does my well water smell like rotten eggs?

A sulfur (rotten egg) smell is caused by hydrogen sulfide gas, which can come from:

  • Sulfur bacteria in the well
  • Chemical reactions in the water heater
  • Natural sulfur in groundwater

Solutions: Chlorination, aeration, or filtration systems can eliminate the smell.

Is well water safe to drink?

Well water can be very safe — often cleaner than city water — but it depends on:

  • Proper well construction and sealing
  • Local groundwater quality
  • Distance from contamination sources
  • Regular testing and maintenance

We recommend testing annually and addressing any issues promptly.

→ Well water vs city water comparison
Why is my well water brown or rusty?

Brown or rusty water is typically caused by:

  • Iron in groundwater: Very common in SoCal
  • Corroding pipes: Older galvanized plumbing
  • Sediment: Disturbed well or dropping water table
  • Iron bacteria: Slimy, rust-colored buildup

Solutions: Iron filters, water softeners, or well rehabilitation.

4 Maintenance Questions

How do I maintain my well?

Basic well maintenance checklist:

  • ✓ Test water quality annually
  • ✓ Check pressure tank air charge yearly
  • ✓ Inspect well cap/seal for damage
  • ✓ Keep area around well clear of debris
  • ✓ Listen for unusual pump sounds
  • ✓ Monitor water pressure and flow
→ Complete maintenance guide
What should I do if I have no water?

Before calling us, check these things:

  • Is the circuit breaker tripped?
  • Is the pressure switch in the "on" position?
  • Did you recently use a lot of water?
  • Are neighbors also without water?

If these don't solve it, call us for same-day emergency service.
